Show them the awesome destructive power of the earth with a slippery, oozing goo they’ll love to get their hands in.

In this article I’ll show you how to make Glacier Goo—a type of Silly Putty that will demonstrate the movement of glaciers.

Why Make Glacier Goo?

Glaciers are pretty fascinating things: massive, moving, blue-and-white mountains of ice that destroy nearly everything in their paths, creating landforms such as U-shaped valleys, moraines and kettle lakes, to name a few.

For hundreds of thousands of years, the movement of glaciers has shaped land through erosion and deposition.

Glacier Goo is a really cool way to learn how glaciers transform the earth and literally move mountains—and you don’t have to wait a thousand years to see the results.
